HDPE paipu ʻāwili paia pālua

ʻO ka wehewehe pōkole:

ʻO ka mea nui o ka HDPE pā pālua corrugated paipu he polyethylene kiʻekiʻe kiʻekiʻe, ua hoʻokuʻu ʻia ka paipu e ka extruder co-extruder mai loko a ma waho o kēlā me kēia, paʻa ka paia o loko a he trapezoidal ka paia o waho.
Aia kekahi ʻāpana hakahaka ma waena o ka pā o loko a me waho. Loaʻa i ka huahana nā ʻano pono like ʻole e like me ke apo kiʻekiʻe, ka ikaika, ke kaumaha māmā, ke kani ʻana o ka leo, ke kūpaʻa UV kiʻekiʻe, ke ola lōʻihi a me ke kulou maikaʻi ʻana, anti-pressure, ikaika hopena kiʻekiʻe a pēlā aku. Hiki ke hoʻohana ʻia i nā ʻāpana geological maikaʻi ʻole, ʻo ia ke pani kūpono no nā paipu hoʻoheheʻe wai maʻamau.
